1. General

The instructions and list of spare parts are applicable to

ShearStream SB ball sector valves in accordance with

catalogue sheet FCD NFEETB4152-01.

2. Lifting

All lifting must be carried out on the valve itself and not

on the actuator. The joint between the valve and the actua-

tor is designed for carrying the operating torque and the

weight of the actuator - see Fig. 1.

3. Receiving Inspection

All valves leaving our plant are inspected and tested in

accordance with the relevant requirements or in accor-

dance with the requirements speciﬁ ed by the purchaser.

Valves equipped with actuators are subject to functional

testing and are adjusted in such a manner that every unit

is completely ready for direct installation in the pipework.

However, in view of damage that may have occurred

during transport, it is advisable that receiving inspection

is performed.

We would suggest the following inspection procedure:

- Check that

the valve delivered is correct in

terms of type, size, equipment

, etc.

- Examine the valve, actuator and valve positioner

regarding possible damages
